Stationary Sources of Air Pollution
Stationary sources of air pollution, including factories, refineries, boilers, and power plants, emit a variety of air pollutants. The Clean Air Act directs EPA to control these emissions by developing and implementing:
-
National Emissions Standards for Hazardous Air Pollutants (NESHAP)
-
New Source Performance Standards and Emission Guidelines for criteria and other air pollutants (NSPS/EG)
-
National standards or guidelines for consumer and commercial products for ozone forming volatile organic compounds (Control Techniques Guidelines (CTG), Alternative Control Techniques (ACT), and Clean Air Act section 183(e) rules)
